PRINTING ATTACHMENT FOR ROLL-PAPER.

SPECIFICATION forming part of Letters Patent no. 651,414, dated June 12,1900.

Application filed January 31,1 900. Serial No- 35441- (No model.)

To ZZZ l whom itmaty concern:

Be it known that I, SAMUEL K. DRUOE, a

citizen of the United States of America, and

a resident of Madeira, in the county of Hamilton andState of Ohio, haveinvented certain new and useful Improvements in Printing Attachments forRoll-Paper, of which the follow: ing is a specification.

This invention relates to certain improvements in printing attachmentsfor roll-paper, and has for its object to provide a device of thisnature which shall be of a simple and inexpensive character and of aconstruction strong and durable and which shall be capable of beingreadily applied, if desired, to rollpaper holders such as are in commonuse or of being manufactured as a part of such rollpaper holders.

The invention consists in a device of this character comprising aprinting attachment for printing the paper from the roll and means forautomatically removing said attachment from printing contact with thepaper after each operation of the attachment.

The invention also contemplates certain novel features of theconstruction, combination, and arrangement of the several parts of theimproved printing'attachment, whereby certain important advantages areattained and the device is made simpler, cheaper, and otherwise betteradapted and more convenient for use, all as will be hereinafter fullyset forth.

The novel features of the invention will be carefully defined in theclaims.

In the accompanying drawings, which serv to illustrate the invention,Figure 1 is a rear elevation of a paper-roll holder having myimprovements applied thereto, and Fig. 2 is an end elevation of thesame. Fig. 3 is an enlarged partial end View of the printing attachment,the hand-wheel of the type or printing roller being omitted. Fig. 4 isan enlarged partial sectional view taken verticallythrough the printingattachment in the plane indicated by line a 4; in Fig. 1. Fig. 5 is anenlarged transverse section taken through the type or printing roller ofthe attachment in the plane indicated by the line 5 5 in Fig. 1. Fig. 6is an enlarged partial View showing one of the bearings for the ends ofthe printing-roller. Fig. 7 is an enlarged partial section taken alongone of the slotted guides of the attachment. Fig. 8 is an enlargeddetail View showing one of the clamping-blocks for holding the endbearings of the printing-roller in place on the slotted guides.

, As shown in the views, the roll-paper holder is of a'well-knownconstruction, having up rights or standards 1 1, connected at theirupper ends by a cross-bar 2, and having centrally-arranged open bearings3 3, in which are held the ends of a shaft 4, on which the paper-roll 5is carried. The device is also provided with a blade 6, along which thepaper may be torn, said blade being held by springactuated arms 7, so asto press at all times on the front face of the roll 5.

8 indicates the type or printing roller of the printing attachment, saidroller being held on a shaft 9, held to turn in openings 10 inbearing-plates or slides 11, one at each end of the roller. Thebearing-plates or slides 11 have each two parallel channels 12 12,spaced apart to receive the arms 13 13 of slotted or forked guides, oneat each end of the roller 8, said arms 13 being spaced apart by slots14, in which play the thicker central parts 15 of the plates or slides11 when said plates or slides are moved up or down along their guides,as is required in order to accommodate the printing attachment to thegradually-decreasing diameter of the paper-roll 5. The guides have theirlower ends 15 perforated for the passage of the shaft 4, on which theyare held at opposite ends of the paperroll 5, and said guides stand inarearwardlyinclined position, their upper ends being secured to thecross-bar 2 by means of'curved braces 16, as shown in Fig. 2.

The bearing-plates or slides 11 are each held to'its guide by means ofan attached plate 17, riveted. or otherwise secured to it and extendedacross the upper ends of the channels 12, these plates 17 being omittedin Figs. 6 and 7 to show the channels 12 be.- neath. The ends of shaft 9project outside the bearing or slide plates 11 and serve to receivehand-wheels 18, as shown in Figs. 1, 2, and 3, by means of which theshaft and the type-roller 8, carried thereon, maybe turned, as will behereinafter explained.

Spiral springs 19 are arranged in the slots let above each slide-plate11, said springs having their lower ends engaged with upwardlyextendedpins 20 on said slide-plates and having their upper ends engaged withsimilar downwardly-extended pins 21 on clampingblocks 22, which havetheir opposite side portions recessed or reduced in thickness, as shownat 23 in Fig. 8, to receive the arms '13 of the slotted guides and havethickened portions 24: between said recessed side portions to fit in theslots 14 of the guides. The clamping-blocks 22 are also provided withclamping-plates 25, adapted to extend over the recessed side portions 23and the arms 13, held therein, being secured to the blocks 22 by meansof thumb-screws 26, which serve to press the plates 25 on the blocks inorder to clamp and hold the latter in adjusted position on the slottedguides. By this construction when it is desired to shift the position ofthe clamping-blocks up or down on the guides it is only necessary toloosen and not to entirely remove the screws 26. 20 and 21 are made intapered form, as shown clearly in Figs. 6, 7, and 8, in order to permitof being pressed tightly inside the ends of the springs 19 and byawedging action to secure the plates 11, blocks 22, and springs 19together for movement along the guides.

The bearing-plates or slides 11 have rearwardly-extended arms 27, theextremities of which have angular slots 28 open at the upper sides ofthe arms and serving to receive the ends of a shaft 29, on which theink-roller 32 is carried, said slots being provided with springs 30,which are pressed, by means of' screws 31, against the ends of the shaft29 in such a Way as to hold the ink-roller pressed elastically upon theprinting-roller 8. The ink-roller 32 has at its central portion anabsorbent pad 33, adapted to receive a supply of ink after the fashionof a rubber-stam p pad.

The type or printing roller 8 has an enlarged or thickened centralportion 34, longitudinally slotted in its periphery, as shown at 3 5, toreceive removable types 36, from which the paper on roll 5 is printed,the ends of the thickened portion 34. of the roller having annularflanges orplates 37 secured thereon, which close the ends of the slots35 in the roller, so as to hold the types in place therein, andare ofdiameters slightly greater than that of the part 3t of the roller. Theplates or flanges 37 are adapted to rest on the surface of thepaper-roll 5 and are notched or serrated in order to insure the rotationof the printingroller from the movement of the paper-roll when the paperthereon is drawn endwise under the blade 0. The flanges or plates 37 arealso adapted for contact with the ink-pad 33 of the ink'roller 32, so asto insure the rotation thereof in contact with the type-surfaces of theprinting or type roller 8, and the project-ing teeth or serrations ofsaid flanges will receive ink from the pad and apply the same to thepaper of the roll 5, so as to print a line of impressions along eachside of the imprint of the type-surfaces of roller 8 upon The pins by itwill be seen that instead of the printingroller being continuouslyrotated from the movement of the paper-roll 5 and printing a continuousseries of impressions upon the paperof said roll the printing fromroller 8 upon the paper, as well as the rotation of said roller and ofthe ink roller 32, is automatically stopped after each full rotation ofsaid printing-roller. The cam devices comprise plates 38, one at eachend of the roller 8, each plate having a projecting flange 39 of roundedform and slotted at one end to receive a small roller or wheel 40, whichprojects beyond the perimeters of the flanges orplates 37 and is adaptedin the rotation of the roller 8 to come into rolling contact with thepaper-r0115, as shown in Fig. 4.

In the operation of the device as the paper from roll 5 is pulledendwise under the bar 6 the rotation of the roll will be imparted to theprinting-roller 8, so as to cause the type-surfaces thereof to make animprint upon the paper, the ink-roller 32 being simultaneously rotated,so as to supply ink to said type-surfaces. When the printing-roller hascompleted'a rotation, its cam-rollers 40, by contact with the paper-roll5, will act to lift said printing-roller, so as to remove itstype-surfaces 36 and flanges 37 out of printing and driving engagementwith the paper-roll 5, so that the paper from said roll 5 may be drawnout to any desired length without being again printed. When it is againdesired to set the printing devices in operation, the roller 8 is turnedslightly by means of the handewheels 18, so as to move the cam-rollers40 out of contact with the paper-roll 5 and permit the typesurfaces andflanges of the type or printing roller to again come in contact forprinting and driving with the paper-roll 5.

The springs 19 serve to hold the type-surfaces of the printing-roller inclose contact with the paper-roll 5 despite any inequalities therein orthe gradually-decreasing diameter of said roll, and the adjustableclampingblocks 22 permit the tension of said springs to be varied andalso permit of being moved down along the slotted guides when thediameter of the roll 5 has been greatly reduced. The slottedprinting-roll 8 also permits of readily changing the type-surfacesthereof when desired; but this changeable feature forms no part of thepresent invention and is non-essential thereto.

The arrangement of the printing-roller with projecting flanges 37,adapted for driving contact not only with the paper-roll, but also withthe ink-roller 32, affords an extremely simple and desirable means forimpartingthe necessary movement to the printing and ink rollers and alsoserves for the printing of parallel lines on the paper along each sideof the IIO imprint of the main type-surfaces 36, so as to give a moreornamental effect to the imprint.

The improved printing attachment constructed as above set forth is of anextremely simple and inexpensive nature and is especially well adaptedfor use in connection with paper-holders, since it permits of printingbut a single imprint upon the paper, instead of a continuous series ofimpressions, as in other devices heretofore provided for this purpose.Also the type or printing roller stands normally with its type-surfacesraised off the paper-roll, so that Whenever desired and without anymanipulation of the printing attachment Whatever a sheet of paper of anydesired length and unprinted may be torn from the roll. It Will also beobvious from the above description of my improvements that the printingattachment is capable of some modification Without material departurefrom the principles and spirit of the invention, and for this reason Ido not Wish to be understood as limiting myself to the precise form andarrangement of the several parts herein set forth. 4

Having thus described my invention, I claim 1. The combination of aholder adapted to.

- whereon said printing-roller is held and having an end extended beyondthe said guides, means for elastically pressing the printingrollertoward said paper-roll, a cam device for removing and holding theprinting-roller out of contact with the paper-roll after each rotationof the printing-roller and a hand-wheel on the extended end of theprinting-roller shaft, substantially as set forth.

2. The combination of a holder adapted to carry a paper-roll, aprinting-roller adapted for movement toward and away from saidpaperroll, means for pressing the printing-roller, when released, towardsaid paper-roll, and a cam device for removing said printing-roller fromcontact with the paper-roll after each rotation of the printing-rollerand comprising a part projected beyond the periphery of theprinting-roller for contact With the paperroll, and a roller held toturn on one end of said projecting part and also adapted for contactwith the paper-roll, substantially as set forth.

3. The combination of a holder adapted to carry a paper-roll, slottedguides at opposite ends of said paper-roll, bearing-plates movof theguides, and springs held in the slots of the guides between thebearing-plates and said blocks and having the said pins wedged in theirends, substantially as set forth.

4. The combination of a holder adapted to carry a paper-roll, guides atopposite ends of the roll, each guide being forked to produce alongitudinal slot in it, bearing-plates movable along the guides, blocksadjustable on the guides above the bearingplates, said bearing-platesand blocks having recesses alined with the slots of the guides, aprinting--roller having a shaft journaled in the bearing-plates, springsarranged in the slots of the guides and means for holding the ends ofthe springs in the recesses in the bearingplates and blocks,substantially as set forth.

5. The combination of a holder adapted to carry a paper-roll, guides atopposite ends of the roll, each guide being forked to produce alongitudinal slot in it, bearing-plates movable along the guides, aprinting-roller having a shaft journaled in the bearing-plates, springsheld in the slots of the guides with their lower ends engaged with thebearingplates, blocks arranged on the guides above the springs, andclamping-plates and screws carried by the respective blocks for holdingthem adjustably in place on the guides, sub stantially as set forth.

6. In a device for printing roll-paper, the combination of aprinting-roller having re duced end portions and an enlarged centralportion provided with longitudinal type-re-.

ceiving slots, annular plates held on the roller at the ends of theenlarged central portion and extending across the ends of the slots tohold the type against displacement and their edges projecting beyond theperimeter of the roller for driving engagement with a paperroll, and camdevices carried on the reduced end portions of the printing-roller andadapted for engagement with the paper-roll for lifting theprintingroller out of engagement therewith, substantially as set forth.
